Bravo Hawaii DOT. Now the Koko Head bound (east-bound, or EB) direction at Makiki has four through lanes between Ward Ave. and Punahou St. With a simple re-stripping, the freeway viaduct over Piikoi St. changed from a total of 6 lanes to 8. That's a 30% improvement for "peanuts."
Before the EB Vineyard Boulevard on-ramp the freeway has its the typical 3-lane configuration, like so:
The new lane is the continuation of the fourth lane that comes from the Vineyard Boulevard on-ramp like so:
The Ward Avenue on-ramp adds a fifth lane but this lane merges onto the fourth lane. Now next to the Piikoi Street on-ramp the freeway is 4 lanes wide!
This location was a perennial midday bottleneck. Now outside the peak hours, flow should be much smoother on both directions. Recall that the west-bound direction was modified from 3 to 4 lanes a couple weeks earlier, as presented here.
